TRY THE API
Verify before your agent trades.
Live, read-only checks. No wallet connection or transactions.
Base connectivity
Check a live Base block and factory deployment.
Discover indexes
Preview live index discovery without paying for quotes.
Connectivity does not guarantee liquidity, safe execution, or contract integrity. Agents must enforce their own transaction policies and verify a fresh wallet-specific quote.
Quote before you move
Request wallet-specific buy, seed or sell plans with minimums. Buys use Indexio's adaptive Base router.
POST /api/agent/quoteKeep keys in your wallet
Sign only after inspecting the contract, fee, minimum output and expiry. Approval and execution are separate when required.

Read wallet shares and USDC directly from Base, with the observation block and actual vault fees. No stale, invented dollar values.
GET /api/agent/portfolio ↗Track real fills
Verify transaction receipts and wallet-level USDC, share changes and gas. Cost basis is labeled partial unless full history is proven.
POST /api/agent/performancePrice the way out
Get fresh sell proceeds and a protected minimum. When your wallet is approved, the endpoint simulates an executable transaction.

Never reuse an old swap route after approval.

Honor quoteExpiresAt and wallet spend limits.
Indexio prepares unsigned transactions; it does not submit trades or manage an agent's funds. Router quote validity is short, and simulation is not a success guarantee.
KNOW THE COST
Built for allocation strategies, not high-frequency scalping.
Indexio's index protocol fee is 1% on entry and exit; an index creator may add up to 1% each way. Swaps, token transfer taxes and Base gas can add costs. Agent strategies should factor those into every trade decision.
BUILD WITH INDEXIO
Integrate your strategy, not a new wallet.
Use any Base-capable wallet stack, including agent frameworks that can call HTTPS APIs and sign EVM transactions. Set allowlisted contracts, position limits and confirmation rules yourself.
